# Short-Description: Start telegraf at boot time
### END INIT INFO
# this init script supports three different variations:
# 1. New lsb that define start-stop-daemon
# 2. Old lsb that don't have start-stop-daemon but define, log, pidofproc and killproc
# 3. Centos installations without lsb-core installed
#
# In the third case we have to define our own functions which are very dumb
# and expect the args to be positioned correctly.
# Command-line options that can be set in /etc/default/telegraf. These will override
